[vtkusers] updating extents after vtkImageClip

[Madhusudhanan Balasubramanian]

Just found that vtkImageTranslateExtent could do this.  

=================================================================

Hi all,
 
when I clip (xmin, xmax, ymin, ymax, zmin = 1, zmax = 1) using vtkImageClip, the getoutput() method returns vtkImageData with extent values: zmin = 1, zmax = 1.   Since, the vtkImageData output contains a single z-plane in my case, it would be much convenient to me if the whole value be mapped to zmin = 0, zmax = 0 (especially, if I use vtkImageMapper, I can just set SetZSlice(0) instead of changing it everytime based on the z-level).
 
I appreciate any inputs on this.
 
Madhu.
